The mechanical advantage (MA) is a number indicating how much a simple machine reduces the effort needed to move a load. The mechanical advantage of a wheel and axle is roughly equal to the Wheel radius divided by the Axle radius.

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..
